SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 406,716, dated July 9,1889.

Application filed September 20, 1888. Serial No, 285,879. (No model.)

To all whom it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut have invented new and useful Improvements in Sheet-DeliveryApparatus for Printing-Machines, of which the following is aspecification.

This invention relates to an improvement in sheet-delivery apparatusserviceable in printing-presses, as set forth in the followingspecification and claims and illustrated in the accompanying drawings,in which Figure 1 shows a side elevation of a sheetdelivery apparatus.Fig. 2 is a plan view of parts shown in Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates a type-bed or lyp'e-cylinder,and B an impression-cylinder. A sheet being fed from the feed-board C istaken by the gripper D and carried between the cylinders A B. Afterbeing thus printed the sheet passes to the delivery traveler or tapes F.A stripping finger sion-cylinder and causes said sheetto passto.

the traveler F. Gears L are shown adapted to actuate the cam K. Thedelivery traveler or tapes F move in the direction of arrow .1, Fig. 2.Rollers G H carry the traveler or tapes F. I

M is a carriage, having rollers N 0 supporting a traveler or tapes P. Onthe shaft of the roller 0 is loosely mounted a gear-wheel Q. A toothedwheel R is firmly secured to the shaft of the roller 0, and a pawl S issecured to the gear-wheel Q, so that a clutch-connection is formedbetween the'gear-wheelQ and roller 0. When the gear-wheel rotates in onedirection, the pawl S glides over the teeth of the wheel R withoutturning said wheel R or the roller 0; but when the gear-wheel rotates inthe opposite direction the pawl S engages the teeth of the wheel R androtates said wheel and the roller 0 and imparts'motion to the traveleror tapes P. V A rack T is applied or fixed to the apparatus, so as toengage the gear-wheel Q. The carriage M has a rack U engaging thegearwheel V. Two gear-wheels V, Fig. 2, are shown, adapted to engage tworacks, one at each side of the carriage M; but one gear-wheel V and onerack U might be made to answer. The gear-wheels V are oscillated by agear-wheel W and a rack-bar X, jointed at Z to the crank Y. The crank Yimparts an oscillating or reciprocating motion to the rack-bar, and apin or arm a, fixed-to the press or machine, holds the rack-bar in gearwith the wheel WV.

' The operation is as follows: A sheet having been printed, said sheetis passed from the cylinder B to the traveler or tapes F, which carrysaid sheet toward the carriage M and deposit said sheet on saidcarriage. The motion of the carriage is such that it is under thetraveler or tapes and about to begin its forward movement at the timethe head of the sheet passes off the traveler or tapes. Said carriage M,moving in the same direction as they sheet, receives the sheet from thetraveler or tapes and conveys it over the receivingtable. The carriage Mthen moves backward or toward the cylinder B, and duringithis motion ofthe carriage the clutch-connection rotates the roller 0, so as to imparta progressive movement to the traveler or tapes P-that is, to move thatportion of the carriage-tapes which carries the sheet toward thereceivingtable I). The sheet resting on the tapes P is by thisprogressive movement of the tapes caused to move off the carriage M tothe receiving-table 1). During the forward motion of the carriage M awayfrom the cylinder B the clutch-connection allows the roller 0 andtraveler P to be at rest. Suitable gears c d, Fig. 2, convey motionbetween the cylinders A B. Pulleys e c are adapted for the reception ofa belt (not shown) to convey motion between the cylinder A and roller G,to actuate the traveler F and keep the traveler F continuously moving.The carriage M is supported by ways f and rollers 9, Fig. 2, so thatsaid carriage can be readily reciprooated by the rack-bar X. As thecrank Y oscillates the carriage M positively in both directions, the useof a spring or weight to restore the carriage to its original positioncan be dispensed with. The traveler or tapes F constitute a simple andeffective delivery apparatus for delivering the printedsheet from theimpressioncylinder L to the carriage M, and as said traveler F candispense with grippers or equivalent mechanism said traveler can becheaply made and contains no mechanism liable to get out of order.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. The combination, with an impressioncylinder, a delivery apparatus,and a receiving-table, of a reciprocating carriage arranged below thedelivery apparatus and on which the printed sheet is deposited by saiddelivery apparatus, and a crank for positively moving said carriage inboth directions, substantially asdcscribed.

GEORGE P. FENNER.
